With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half of the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half of the entrance pupil diameter (HEP) of one surfaceand the thickness (TP) of the lens, which the surface belonged to, onthe optical axis (i.e., ARE/TP) has to be particularly controlled.

In the currentembodiment, each of the signal transmission elements SC1 is a gold wire.The sensor holder SB is disposed on the circuit substrate EB, and theimage sensing component S and the signal transmission elements SC1 aresurrounded by the sensor holder SB. In this way, when an image opticalsignal is sensed by the sensing surface of the image sensing component Sand is transformed into an electrical signal, the electrical signalcould be sent to the circuit contacts EP via the image contacts IP andthe signal transmission elements SC1, so that the circuit contacts EPcould transmit the electrical signal to other external components forsubsequent processing.

In the current embodiment, the fixedbase FB1 is made of plastic material and is opaque, and has a focusinghole penetrating through both ends of the fixed base FB1, so that thefixed base FB1 is hollow. The fixed base FB1 is disposed on the sensorholder SB, so that the image sensing component S is located in thefocusing hole. The movable base MB1 has a receiving hole penetratingthrough both ends of the movable base MB1, so that the movable base MB1is hollow, wherein the receiving hole directly faces the sensing surfaceof the image sensing component S. More specifically, the movable baseMB1 includes an inner holder LH1 and a lens barrel B1, wherein the innerholder LH1 is disposed in the fixed base FB1 and is located in thefocusing hole, and is controllable to move relative to the fixed baseFB1. The inner holder LH1 has an inner through hole DH1 penetratingthrough both ends of the inner holder LH1, so that the inner holder LH1is hollow. The lens barrel B1 is disposed in the inner holder LH1 and islocated in the inner through hole DH1, and is capable of being driven bythe inner holder LH1 to move relative to the fixed base FB1. The lensbarrel B1 has the receiving hole penetrating through both ends of thelens barrel B1, so that the lens barrel B1 is hollow.

The fixed base FB1 has a predetermined thickness TH1 (i.e., a distancefrom an outer wall of the fixed base FB1 to an inner wall of the innerthrough hole of the inner holder LH1 in a direction perpendicular to theoptical axis of the lens group L), and a maximum value of a minimumlength on a periphery of the fixed base FB1 perpendicular to the opticalaxis of the lens group L is denoted by PhiD. In addition, the lensbarrel B1 has a predetermined thickness TH2 (i.e., a minimum thickness),and a maximum value of a minimum length on a periphery of the lensbarrel B1 perpendicular to the optical axis of the lens group L isdenoted by PhiC. In the current embodiment, a glue is coated between thelens barrel B1 and the inner holder LH1, and the lens barrel B1 and theinner holder LH1 are fixed to each other via the glue, so that the lensbarrel B1 is disposed in the inner holder LH1 and is fixed in the innerthrough hole DH1.

In addition, theopposite surfaces (object-side surface and image-side surface) of thefirst to the seventh lenses could be aspheric that could obtain morecontrol parameters to reduce aberration. The number of aspheric glasslenses could be less than the conventional spherical glass lenses, whichis helpful for reduction of the height of the optical image capturingmodule.

The driving module could be a voice coil motor (VCM),which is used to move the lens for focusing, or could be an opticalimage stabilization (OIS) component, which is used to lower thepossibility of having the problem of image blurring which is caused bysubtle movements of the lens while shooting.

To meet different requirements, at least one lens among the first lensto the seventh lens of the optical image capturing module of the presentinvention could be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect could be achieved by coating on atleast one surface of the lens, or by using materials capable offiltering out short waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing module in the present invention could be either flat orcurved. If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane could be decreased, which is not only helpful to shorten thelength of the optical image capturing module (TTL), but also helpful toincrease the relative illuminance.

[Second Optical Embodiment]

As shown in FIG. 3A and FIG. 3B, an optical image capturing module 20 ofthe second optical embodiment of the present invention includes, alongan optical axis from an object side to an image side, a first lens 210,a second lens 220, a third lens 230, an aperture 200, a fourth lens 240,a fifth lens 250, a sixth lens 260, a seventh lens 270, an IR-cut filter280, an image plane 290, and an image sensor 292.

The first lens 210 has negative refractive power and is made of glass.An object-side surface 212 thereof, which faces the object side, is aconvex spherical surface, and an image-side surface 214 thereof, whichfaces the image side, is a concave spherical surface.

The second lens 220 has negative refractive power and is made of glass.An object-side surface 222 thereof, which faces the object side, is aconcave spherical surface, and an image-side surface 224 thereof, whichfaces the image side, is a convex spherical surface.

The third lens 230 has positive refractive power and is made of glass.An object-side surface 232, which faces the object side, is a convexspherical surface, and an image-side surface 234, which faces the imageside, is a convex spherical surface.

The fourth lens 240 has positive refractive power and is made of glass.An object-side surface 242, which faces the object side, is a convexspherical surface, and an image-side surface 244, which faces the imageside, is a convex spherical surface.

The fifth lens 250 has positive refractive power and is made of glass.An object-side surface 252, which faces the object side, is a convexspherical surface, and an image-side surface 254, which faces the imageside, is a convex spherical surface.

The sixth lens 260 has negative refractive power and is made of glass.An object-side surface 262, which faces the object side, is a concavespherical surface, and an image-side surface 264, which faces the imageside, is a concave spherical surface. Whereby, the incident angle ofeach view field entering the sixth lens 260 could be effectivelyadjusted to improve aberration.

The seventh lens 270 has negative refractive power and is made of glass.An object-side surface 272, which faces the object side, is a convexsurface, and an image-side surface 274, which faces the image side, is aconvex surface. It may help to shorten the back focal length to keepsmall in size, and may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The IR-cut filter 280 is made of glass and is disposed between theseventh lens 270 and the image plane 290. The IR-cut filter 280 gives nocontribution to the focal length of the optical image capturing module.

The parameters of the lenses of the second optical embodiment are listedin Table 3 and Table 4.

As shown in FIG. 4A and FIG. 4B, an optical image capturing module ofthe third optical embodiment of the present invention includes, along anoptical axis from an object side to an image side, a first lens 310, asecond lens 320, a third lens 330, an aperture 300, a fourth lens 340, afifth lens 350, a sixth lens 360, a seventh lens 370, an IR-cut filter380, an image plane 390, and an image sensor 392.

The first lens 310 has negative refractive power and is made of glass.An object-side surface 312 thereof, which faces the object side, is aconvex spherical surface, and an image-side surface 314 thereof, whichfaces the image side, is a concave spherical surface.

The second lens 320 has negative refractive power and is made of glass.An object-side surface 322 thereof, which faces the object side, is aconcave spherical surface, and an image-side surface 324 thereof, whichfaces the image side, is a convex spherical surface.

The third lens 330 has positive refractive power and is made of plastic.An object-side surface 332 thereof, which faces the object side, is aconvex aspheric surface, and an image-side surface 334 thereof, whichfaces the image side, is a convex aspheric surface. The image-sidesurface 334 has an inflection point.

The fourth lens 340 has negative refractive power and is made ofplastic. An object-side surface 342, which faces the object side, is aconcave aspheric surface, and an image-side surface 344, which faces theimage side, is a concave aspheric surface. The image-side surface 344has an inflection point.

The fifth lens 350 has positive refractive power and is made of plastic.An object-side surface 352, which faces the object side, is a convexaspheric surface, and an image-side surface 354, which faces the imageside, is a convex aspheric surface.

The sixth lens 360 has negative refractive power and is made of plastic.An object-side surface 362, which faces the object side, is a convexaspheric surface, and an image-side surface 364, which faces the imageside, is a concave aspheric surface. The object-side surface 362 has aninflection point, and the image-side surface 364 has an inflectionpoint. It may help to shorten the back focal length to keep small insize. Whereby, the incident angle of each view field entering the sixthlens 360 could be effectively adjusted to improve aberration.

The IR-cut filter 380 is made of glass and is disposed between the sixthlens 360 and the image plane 390. The IR-cut filter 390 gives nocontribution to the focal length of the optical image capturing module.
